BERRY sIIocKER INCORPORATED, or on DELAWARE.

WILMINGTON, DELAWARE, A' coRPoRA'rIoN GRAIN sHooKER.

The shocker of the present invention is of the general type shown anddescribed in the Bert C. Berry applications, Serial No. 318,- 738, iledAugust 20, 1919, and Serial No. 446,843, tiled January 8, 1921; and thepresent invention is directed to numerous features of improvement in thestructure and operation or the various working part-s included in ashocker of the type indicated.

The grain shocker oit ploys an open sided pan or sheaf receiver, intowhich the sheaves are dropped from the binder with which the shocker isassociated. The sheaves fall into the pan with their butts projectingforward and accumulate in the pan until the number required toconstitute a shock has been accumulated. At this point trip mechanism isoperated which drops the pan until the tread members with vhich the panis combined engage the ground, after which a complete rotation of thepan is effected, upending or butting the shock upon the ground, andcausing the pan to somersault over the top ot' the shock in its returnto normal or receiving position.

The pan and tread membersare carried by a pivoted inner frame, and theseelements in combination constitute in effect a dump cart, which indepositing the shock iunctions in a measure independently of the tourwheeled frame, which constitutes the supporting element for the pan andtread members while the shock is being accumulated.

llie present invention is directed to the toll owing instrumentalitiesFirst, to the mechanisms provided for packing down the individualsheaves as they accumulate in the pan, until the resistance ot theaccumulating pile of sheaves against the packer mechanism serves toeffect the operation of trip mechanisms which` release the pivoted inner'frame and allow the tread members to engage the ground.

Second, to the means provided for steadying the up-ended shockand-preventing the eii'ect otl its acquired momentum from toppling overthe shock as its butt end is deposited upon the ground and during theinterval ot time. that the pan is passing forwardly over the top of thedeposited shock.

Third, tines, which are designed to align the butts of the sheavesduring the period ot accumuthis general type em-v to the arrangement ofthe butting.

lation, and to spread the butts laterally to 'afford an extended basefor the completed shock. f f

Fourth, to the mechanism for suspending the delivery of sheaves duringthe dumping operation by correlated mechanisms, which are eiiiective toopen the gate and allow the delivery of sheaves only during theaccumulating period.

Fifth, to the means for correcting the tore and aft alignment of thesheaves with respect to the pan.

Finally, to the general construction ot' the machine as a. whole and thecorrelating and timing of the several mechanisms to operate inharmonious relation to one another.

rlhe shocker is built Within and supported by a main frame, whichcomprises a pair of spaced side rails 10, 'elevated at-their forwardends 11 and connected through .the medium of corner bracket castings12-to a cross front rail 13 which isprovided With an eye 14 .to receivethe rear Aend of a diagonally disposed draft bar 15, which is connectedwith the draft mechanism for the hinder. "The corner bracket castings1,2 are extended forwardly to afford socket journals 16 which receivetheupper en'dsof caster pintles 17 Whichjournal front caster wheels 18located beneath the inner and outer front `corners of the structure. y

The frame is supported at its rear end by outer andinner ground wheels19 aud/.20, which constitute the sources of power for the operation ofthe packing and eleva-ting mechanisms presently to be described. ATheside rails of the main frame :are h-eld `and braced in suital'ily spacedrelation yby the provision of a rear cross frame 217 of in verted Ushape, Which is connected atits center point to the rear depending leg22 of fore and aft top frame 23, the forwardv leg 24 of which extendsdownwardly and Vmakes a connection with the `forward cross rail 13 ofthe main frame. This arrangement affords a vmain frame, Whichis open atits rear end to clear the deposited shock, and is supported centrally insuch manner as to afford amp-le unobstructed Working space for therotating movements of the-pan.

The mier panesapp ortc'ag frame.

The front bar ofthe main frame constitutes a point of pivotal attachmentfor an inn-er frame, comprising outer' and inner side arins25 and 26,which are integrally connected at their forward ends with a crossconnectingirod 27, (see Fig. 6) which gives to the inner frame the formof a horizontally disposed U-shaped figure open at its rear end;` andthe inner frame is pivoted to rock on va horizontal transverse axis, bythe provision of journal plates 2S which pivotally connect the forwardcorners of the inner frame With the corresponding cornersvof the inainorsupporting frame. The inner frame furnishes a mounting for thesuspension of the open sided pan 29 which diverges from rear tofrontandis provided in its center with 'zt-longitudinally extending chan-nel ordepression 30 of a size to receive and initially position the firstsheaf delivered,

-' edges 'ofz the panaa'reflreinforce'd by the f pro- 'vision of sidefbarsfl, which furnish the main elements of a supporting iframe orcradle 32 Which affords sufficient rigidity to the pan as a Whole.

The pan is associated with a pair of tread ii'ien'ibers' of arcuateformation, the normally lower portion 34 of each treadmember .beingflattened vto clear the ground When the pan is in its normal orreceiving position. The "flatt -med` portions are formed to extend insubstantial parallelism with the bottom edges of the painand the treadsand pan form in effect :a rigidly united structure Which .moves as aunit when the tread inembers .are brought into .ground engagement.Thepan is united tothe tread membersby the provision of rearconnecting'bars 35 and front connecting bars 36, one of tlielat ter being showninFig. 3.

yThe tread members are suitably braced by radial brace members 37suitably vdisposed to afford the necessary rigidity to permit the loadin the pan tobe deposited Without unduly straining or rocking` thestructure as a Whole. lThese braces :areconnected With partspresently tobe described, Which in turn aregpivotally mounted With respect to .theside arms of the inner Vframe on each side, so that the pan, the treads,and all pon tions of the structure which rotate in unison With themovements of the pan will rotate about an axis having a definite bearingpoint yvith respect to the inner frame.

The veeleer cmd trip mechanism.

The packer and trip mechanism is located on the 'outside of the pan, andis illust 'ated in detail in Fig. 4. lit a point coincident with theaxis of rotation of the pan is 'located a stub shaft 39 which isjournaled through abracket bearing 40 carried by the outer rail 25 ofthe inner or oscillating frame The shaft at its outer endt has splinedthereto a main sprocket Wheel 41 which imparts rotation to a bevel facedinner :gear 42 located between the pan andthe adjacent rail 25. A centerbracket casting 43 is freely mounted upon the shaft 39 behindtlie innerbevel faced gear 42, and this casting 43 furnishes a center connectionfor the brace bars 37 and 38, and yfurnishes ahub 'for the outer treadmember.

lThe main sprocket Wheel 41 engagesa sprocket chain 44 which is carriedYaround anvidler 45 mounted upon a swinging arm 4b pivotally supportedat its upper end from a plate 47, Which is normally heldin advanced,position by the action of a spring 48 (see Fig. rfhe plate 47 ispivotally mounted Within a recess in the bracketl bearlli) ing 40 and isprovided with a stop 49 for limiting the freedom of movement between theplate 47 and the arm 46, which two elements are intended to movesubstantially in unison save for the slight freedomjof action indicated.The plate-47 is provided with a rearwardly extendingv finger 50 whichlies immediately beneath a spring-backed detent finger 51 on atrip dog52, which engages a notch 53 in the forward edge of a segment bar 54,which bar has a radius of curvature concentric with the axis of movementof the oscillating innerl frame; and' the bracket bearing 40 is providedwith a slotted guide extension 55 which embraces the seg# ment and isdesigned to ride thereupon without permitting any appreciable lateral ortlistortional movement of the parts, this ar; rangement serving tosteady and support the inner frame during its up and down movements, andto afford the necessary support to permit the overturning movements ofthepan. The latch dog and segment may be duplicated on the opposite sideof themachine and operated through themedium of companion draw rods,which connect with companion rocking fingers 57 at the opposite ends ofa rock shaft 58 journalled in parallel relation to the .forward crossconnection 'for the oscillating inner frame.

The center` bracket casting 43 which is mounted to rotate about the stubshaft 39 carries on the side normally to the rear a journal bracket 59which journalsja crank shaft GO having at its normally forwardend abevel pinion 6l which meshes with the bevel faced gear 42, and theopposite end of the shaft carries a crank 62 having pivoted thereto alink 63 which .connects with a packer crank 64 outwardly projecting froma packer rock shaft G5 jour-nailed in parallel relation to the outeredge of the pan. The packer crank, being longer than the driving crank62, will have the rotary movements of the latter 'transformed into anoscillating movement, thereby rocking the packer shaft 65, by theemployment of power derivezil from the advance of the machine. Thepacker shaft is providedv with a pair of tines or lingers 66 which, whenthe shaft is rocked, will. swing downover the open upper side thereofand press upon the sheavesdeposited therein, after the pile of sheaveshas risen to a given point, and thereafter rthe oscillation of the tineswillv subject the parts ,to an increase in lpressure as the pile isfurtherI accumulated.

The sprocket chain 44 passes over a rear sprocket wheel 67 driven by therear outer ground wheel, so that the chain will be con-y stantlyrotated, and this rotation will continue-to oscillate the packer tinesor lingers until the pile on the pan has risen to such apoint that thepressure of the tines against the accumulated pile will prevent thenormal vlinger at the tail end of the trip dog, thereby releasing thedog latch and allowing the pivoted inner frame to fall until the treadmembers engage the ground. Thereafter the pan will rotate with the treadmembers and associated parts, which rotation will carry the journalbracket 59 around the axial center of the stub shaft39 at a rate uniformwith the speed ofl rotation imparted to the stub shaft by the travel ofthe sprocket chain, so that during this period vof the operation norelative rotation will be imparted by the bevel faced gear through theengaged pinion, which holds the packer tines inl compressed relationagainst the upending shockuntil the same has been butted upon the groundin a vertical position. This pressure will. be maintained against theshock at apoint slightly below the head of the shock, the tines beingpositioned with a view of supporting the shock at this point, whichallows the butts to expand during the upend ing operation. After theshock is upended, the continued advance of the machine will cause thepressure tines to travel away from the now stationary shock as the panis swept around in its continued return movement toward its receivingposition. To accommodate these movements, the gear ratio between thedriving sprocket 67 and the driven sprocket 4l is commensurate with thecircumferential ratio between the ground wheel 19 and the tread member253, which insuresthe proper rotation of the intcrlocked bevel gearswithout the transmission of nio-- tion to the packer members during therotan tive cycle of the pan. r v

The cov/Wesson lshock during the upending operation and support the sameas the pan sweeps over the top ofthe butted shock, and with this end inview the compressor mechanism is mounted and ,actuated in such a manneras to carry its effective point of contact toward the rear as themachine advances forwardly, and to maintain this contact until the panis well above the deposited shock, thereby counteracting any tendencyfor the pan to upset the shock as it begins its sweep over the topthereof. In designing this mechanism the factors involved pertain to theforward advance of the machine as a whole, to the rotative movement ofthe pan, and to the varying components ofl vertical and horizontaltravel imparted to the compressor members by the rotationl ofthe pan onwhich they `are mounted. `These devices will `new be described indetail.

Figures 7 and 9 illustrate the compressor mechanism `and associatedparts. The compressor arm 68 is mounted upon a compresH sorrock shaft'69 which is=`oifset at the point TO to amplify the effect ofthe rockingmovements of the shaft 69. The slraft'is journalled withina sleeve 7land is-acted1upon by a Coilspring 72 which-'normallyhasthe eilect ofswinging the offset outer en'd of the shaft with the compressor varmGS'n'iounted thereon intoupward position, so that the arm -vrill liehaelt froni=the-open mouth-of the pan insuch position as toYail'ordnoobstruction tofthe depositing ofrthe sheaves therein.

The sleeve''l, as indicated in Fignfis provided with `a laterallyextending trunn-ion 73, whichis entered througha journal 74 carried bya'braclret T''bolted orot-herwise secured to the edge of the pan, ortoportions of the structure iixedly -associatedwith the pan, andthetrunnion earriesiixedly secured to its'outer end a small gear segmentTNG whichl` meshes with a large lgear segment 077, the ratio -shownbeingtwolto one, ,for fthe purpose of speeding' the swinging move-ment of thepressure armtoward the-back of 'the pan at thefproper point in' thetiltingE `of the The large segmentl 71`is carried by aibell crank` arm78,'-whichispivoted vat the endof apintle 79 outstanding from the sideof the pan, and the outer end of the bell Acrank farm carries a roll-erSOWhichlrides uponl afiXed cam 81 which is carried by the adjacentirailof the oscillating inner frame, Whichsarm also carries `at its end laijrourn'al 'head "82 which receives and ljournals the outwardly projecting trunnion 83'v of Lay icnadletbar, which passes-under vthe pan,`said .trunni'on being alined with the stub shaftBQnon theopposite sideof the pan, so that the alignment of these members fixes the axis aroundwhich the pan revolves.

vrlhe cam 81as actually constructed, is shrouded, as shown inFigrt, butin Fig-9 the parts `are indicated diagrammatically Vto better illustratethe co-operat-iverelation, and in this ligure thel'cam .is illustratedwith 'the shroud removed. The rear end .of the cam is conigured tosubstantially :therarc of-a circle, with the trunnion 83 as -a -center,but `the forward port-ion of the cam protrudes quite;abruptly,\=sothatas the pan revolves about the trunnion kv8B as a center, the roller willinitially ride freely over ldie cani without .having any relativemovement imparted thereto, but, as 'th'e cycle of revolution -iscontinued, .the roll-er 'will encounter the fprotuberfant forward "endof the cam, thereby rocking' the 'bell crank arm 78 and causing arotative movement vof the large segment in an inw-ard directiomwhichwill impart 'a correspondingly amplified movement to the small segment,and Vthrough it tothe compressor rock shaft, which vwill be sweptdownwardly, as regards the base of the pan, concurrently with theforward and upwardmotion-of the rear portion of the pan as'it tiltsforward in ythe operation of upending the shock. A

Prior -to `Ithe lmotions above described, :it is essential thatthecompressor 'arnr'68 be rocked' downwardly into transverse relation tothe accu-undated shock 'within the pan, in `order'fto establish laneffective contact therewith priorto thebeginning of the up endingn-ioefements. To "ell'etfs't this result, the compressor rock shaft, atits point, of forward lemergence from the sleeve 71, is provided with alatch head 84 having 'anotch 85adap'ted1to -b'eL engaged by a dogSGwhich is pivoted fto a lug '87 depending from the sleeve 7l. The 'headS4 is provided with atail'pieee'88, and vthe 'dogis likewise providedwi'tlr a tail piece I89,*both` of whichE tail pieces are-adapted'to-rideuponand be supported by a -stop finger 90, `Whielrextends in a#substantially fore and aft direction and is carried by an =upstandingarm 91 pivotally mounted at its ylower Yend in a fittiug'QQ carried bythe 'frame arm 25, a spring '193 serving lto lhold, the "darm vv91 `inretractedposition. 1lt lwill be observedthat thelatch head 84; andthedog 86ers mounted for imovementl on separated centers, and the resultofthis arrangementis-that as the pan begins to rotate about the trunnion83,"the` tail piece89 of the dog, being mounted upon -a lower center,ywill first be released from'fengagementbyz'the stop finger 90 and vwillfall down into positionto engagefthenotch- 85, which through ftheeontinued engagement n of the 'tai'lpiece 88 with the 'stop Y)willberotate'd u'ntila latching of the parts is effected. lThis movement of'the parts causes a rocking of "the compressor' rock shaft and aswinging down ofi the compressor arms across the shock in the pan duringthe -initial increment 'of -Jthe pan, and after vthe fparts larelatched, las yabove described,'the compressor arms will be held incrosswise =relation `against `rota-tive tension-ofthe spring 72,and-thisflocked relation will continue runtil 'the cyclehas beencompleted, at which p'ointthe priorengagenientfof vthe dogftail'piece 89with 'the stop finger 90 will unlatch the r`parts andallow thecompressorarmsfto Aspring back vto ver tical position preparatory tothe: subsequent depositing of the vsheaves yin the building up of thenext su'cceedingshock.

The lefva'tor.

The-'elevator Afor liftingtheisheaves from the lbinder .deck ito '.thepointio'f :disch-arge above the pan is Well illustrated in Figs. 3

and 6. It consists ot a frame comprising side rails 94 which compriseguidetvays tor the vupward Hight ot conveyor chains 95 having -cro'ssbars 96 provided With the usual tines or fingers which project at anangle to the guideways during the upward flight and descent'in parallelrelation to the chain, atter the manner usual in such constructions. Thechains run over the usual sprocket Wheels, which are driven byintermeshing bevel pinions 97, Which derive power from the sprocketchain98 driven byl the inner rear ground Wheel, but since these features arecommon in structures of this kind it is not deemed necessary to furtherdescribe the details. f

The elevator as a Whole is carried by brackets 99 which ext-end upwardlyat an angle from the ends ot' a supporting bary 100, which ends areentered through a pair lof clips 101 adjustably mounted upon theproximate side rail 10 ot' the main `frame, which arrangement permitsthe elevatorto maintain a liXed tore and aft relation to the binderdeck, and at the same 'time permits the shocker asa Whole to be adjustedin a fo-re and att directionin order to bring the pan into properrelation to the delivery point for the sheaves, which is desirable inorder to accommodate the shocker to sheaves ot varying length and toinsure the proper deposit thereof Within the pan.

The sheen" arresting and pcm locking mech- (mism.

During thedelivery of the sheaves to the pan it is necessary toprovidemeans for locking the pan 'against tilting or oscillation, and also toprovide Jfor the recurrent opening ot the gate, which permits the downpassage ol the sheaves to the pan, and these mechanisms will now bedescribed.

The supporting bar 35, which connects the rear end ot the pan to theproximate tread member, is adapted, on its up swing, to ride over theshoulder latch 102 formed on the lower end ot the stop bar 103 Whichhangs trom the rear arch 21, which latch Will spring back sutlicientlyto permit the bar 35 to engage the shoulder, and as the bar slips overtheshoulder it will engage a stop 104, so that it will be held vfirmlylocked between the shoulder and the stop during the accumulation ot thesheaves in the pan. The engagement with the shoulder is sutiicientlyslight, lio-Wever, to cause the parts to clear one another when theoscillating inner trame is unlatched, the pivotalcenter of the innerframe being so arranged that the ita-lling ot the trame `and pan Willoccasion a slight forward movement ot these members, so that the panxAand 'associated parts Will clear the stops Whenthe panbegins to rotate.p

The oscillating` packer shaft is provided, at its rear end, With a bentlinger 105, which oscillates -up and down as the packer shaft is rocked,Which finger coacts with a centrally pivoted rocker 106 carried by thebar 235, thereby lifting the opposite end ot the rocker and causing thesameto engage 'with the inner end ot a bell crank lever 107 pivoted tothe bar 103. The bell crank 107 is connected by means of a draw rod 108with a spring 'controlled latch dog 109, the tooth 110 ot which engagesWith a rlatch head 111 carried by a gate shaft 112, which shaftconstitutes a supportingr head for a series ot tines 113, 4whichconstitute a gate .tor the arresting ot the sheaves, the tines coactingWith a series ot obliquely disposed slide bars 11dextending in obliquelydownward relation from the top ot the elevator, so that when the gate isheld in closed position, as indicated in vFig. 8, the gate tines andslide bars in unison Will provide a troughv shaped open receptacle torthe momentary arresting ofV the sheaves in their progress to the pan.This arrangement also insures a correct fore and-aft position ot thesheaves at this point, so that they Will descend'to the pan vin certainand orderly progression.

So long as the pan remains in locked horizontal relation, the finger105, at the tail end ofthe packer shaft, Will With each return movementeffect an unlatching ot the gate controlling mechanism, so that the release and falling of the she-aves Will occur in alternate timed relationto the active movement-s ot'the packer, so long as the bundles areaccumulating in the pan. This insures against interference otthe sheaveswith the packer mechanismen its ret-urn movements, and at the same timeprovides automatic mechanism for suspending the delivery' ol' thesheaves during the period ot rotation ot' the pan in upending theaccumulated shock, since the latch releasing mechanism is operated onlyduring the time the pan occupies its normal or horizontal position, thegate relmzining locked during the delivery ot the s oc r.

In order to insure a correct positioning ot the sheaves during theaccumulating period, and to provide tor a spreading ot the base ot theshock during the upending thereof, a plurality of butting tines 115 areprovided, the upper ends ot Which are secured to a cross header bar 116which is supported upon the front leg 24 ot the top arch, and theabutting tines are arranged in downwardly diverging relation tov oneanother, the lower ends 117 being given a zigzag or sinuous.configuration crossWise ot the pan, which zigzag arrangement increasesthe eftective lateral dimension ot each tine at its liti) lower-end, andy'facilitates the separation and spreading of the grainstalks, so thatas the pan is upended'the grain stalks composing the butt end oftheshock will be laterally separated and the butt end distended to affordan enlarged basefor the shock.

Adjustable tread shoes.

Each of the tread members is provided on its periphery with anadjustable tread shoe 118, which is pivoted at its forward end 119,and-secured at its rear end by an adjustable clip 120, so that theradius of action of` the arcuate tread members can be increased ordiminished 'within given limits, the tready shoes being located inproper position to occasion an augmented lifting effect atthe time thepan is clearing the deposited; shock, andthe shoe members are madeadjustable in order to accommodate the mechanism to shocks ofvaryingheight.

The axis of the pan is located at a point below the center of each treadmember, and forwardly thereof, so that the liftingy effect of the treadmembers, irrespective of the shoe attachments, will be at a maximumduring the time the; pan is clearing the deposited shock, and during thecycle of operations the oscillating inner frame and pan will, ofcourse,move up and down in conformity with the movements occasioned bytheriding of the tread members over the groundl surface;-

T/re. operation.

In operation, with the pan in horizontal or receiving position, thesheaves will be carried by the elevator and discharged onto the slopingguide bars 114 in horizontal relation with their butt ends forward. Eachsheaf will be momentarily arrested bythe gate as the packer tines areswung down over the open sidey of the pan. As the tines return toupright position, the gate will open andthe sheaf` will be dropped intothe pan. The rst sheaf will assume a position within the depressedcenterportion of the pan and constitute a base or foundation around andabove which the remaining sheaves will be accumulated in symmetricalarrangement. Ata given point in the accumulating of the shea-ves'thepacking tines will begin to exert pressure against the sheaves, tendingto. force them down into a compact mass, and after the-sheaves haveaccunmlated to. a. predetermined amount the pressure of the packinglines will increascsto a degree sufficient to overcome the tension ofthe spring,` which normally tends to retract the idler over which thepacker drive chain passes. This will' arrest the free travel of thechain, and the pullthereofagainst trie idler will effect an unlatchingof the-oscillating inner frame witlrithe pan and tread members rigidlyassociated therewith. The tread members will thus be dropped to positiontoengage-the ground andthe revolution of thepan will begin.

As the pan'begins to revolve, the compressor members on fthe oppositeside of the panwill begin to act. Thefirst operation of the compressorshaft-will be a partial rotation thereof in such direction as to throwdown-the compressor arms to embrace the shock at a point somewhat toftherear of the center, andthe-shock will thus be held rmly within the panby the conjointact'ion of the packer and ycompressor members. As the panis upended, the travel of the roller 80 along the cam 81 will effectapartial `rotation of the intermeshing gear` segments, which willoccasion a back sweepv of the compressor shaft toward the base of thepan concurrently with the turning movement ofthe pan in a forwarddirection., By the time thel pane has assumed a substantially verticalposition, the shock will be butted uponthe grounch but the arcuate sweepof the-rear-l end of the compressor shaft will continue, in a downwardandrearward direction, thereby firmly supportingand forcing down theshockl against the ground as the machine advances to clear the shock.The compressive movement of the shaft is speeded or amplified by theadoption of a multipli-ying gear ratio, which ratio is chosen withfdueregard to the length olf/the compressor shaft and the rotative movementof the pan, with the result that the active end of the compressor shaftwill move rearwardly as the machine advances and maintain contact withthe shock for a sufficient length of time to insure against a'topplingover of the shock as the pan sweeps over thetop of the shock .on itsreturn movement.

The, arrangement of the butting tines is such that as the shock is beingupended the butt ends of the grain .stalks composing the sheaves will belaterally, separated and the base. of the shock distended, the zigzagvrangement of the individual tines and their divergence from. thevertical center line serving to afford sufficient resistance to1 thevmovement of the butt ends to yeffect a substantial spreading ofthe baseof the. shock.l

After the shocklias been delivered, the continued ground Contact of thetread members will carrythe pan around to its origina-l position, theacquired momentum serving to swing up the pan toY latching-posit-ion. sothat the subsequent oscillation of the pan will be prevented and the panpositively maintained in horizontal position during the a eci i mulatingperiod.

The arcuate guideIbai-s 11 in; engagement with' the opposite rails oftheoscillating inner fraaiev servesto insure adequateuguiding and supportforthe free ends of vthe-oscillating Vframe and to guard the.k sam-eagainst torsional strains and to insure a: positive llO positioning ofthe operating parts at all times.

Although the combined packer and trip mechanism above described isprimarily designed for usein connection with a grain shocker, it isevident that it'might be effectively employed in connection with otherclasses of mechanism in Which it is desired to automatically effect atripping of the parts by an increase in the pressure, due to anaccumulation of' material in contact With the packer mechanism, and itis not the intention, unless otherwise indicated in the claims, toconfine the use of the combined packer and trip mechanismt'o grainshockers. The implement as a Whole is so designed as to be entirelyautomatic in its operation, the various mechanismsbeing rsotimed andharmonized in action as to perform the cycle of operations necessary inthe accumulation and deposit of shocks of grain Without any. attentionon the part of the driver of the harvesting machine; and at the sametime the various mechanisms are adjustable to meet the requirements ofgrain sheaves of varying Vheight and to insure a proper accumulation ofthe same.
